the prompt, if you want to run it on your own kitchen:

build a playable 3d browser game of my kitchen: a small kitchen, fridge on the left, stove with two pans in the middle, sink under a window on the right, wooden table with two chairs. first person, i walk with wasd and look with the mouse, open the fridge, grab ingredients and cook one dish at the stove. single index.html, three.js from a cdn, no build step. it has to run when i open the file. when it works, stop.

muse --model muse-wonder-1.0 --reasoning-effort xhigh "..."

notes: opus thought for about 4 minutes before writing a line, then tested its own game with playwright. muse code has no cost meter, so wonder's dollar is its session log priced at the list rate. the clip is both finished games played afterwards by a script doing the same moves in each. the only change is one line in opus's file so the script can read the player position
